Italian "Scallion" Salad

Thanks to BubbleCrumb for this recipe. This is the salad we had on Christmas Day and it was such a hit we had to remake it 2 days later. I varied the ingredients according to tastes and what I had on hand but basically it's the same as follows:

6 cups torn lettuce leaves

8 ounces hard salami, julienned

6 ounces provolone cheese, julienned

1 cup shredded mozzarella cheese

2 medium tomatoes, chopped
1/2 small red onion, diced

1 (6 ounce) can pitted ripe olives ,

drained
2 small jars marinated artichoke hearts, drained

4 scallion stalks, minced (green onion)

1 (8 ounce) can tomato sauce

1/2 cup vegetable oil

1/4 cup red wine vinegar

1 teaspoon sugar

1 teaspoon salt

1 teaspoon dried oregano

1/2 teaspoon garlic powder

1/4 teaspoon pepper
12 pepperoncini

Start with the dressing. Mix the tomato sauce, oil, vinegar, sugar, salt, oregano, garlic power and pepper and refrigerate for at least 1 hour.

Arrange the salad:
Begin with the greens (red leaf mixed with romaine makes it look pretty and festive).
Top with half the shredded mozzarella cheese.
Next layer on the Italian salami, sliced into strips.
Top this with the sliced provolone.
Add the tomatoes.
Then the diced red onions.
Black olives...whole if you have picky eaters or sliced if all enjoy this.
Now 4 diced scallions.
You can add the artichokes if you all enjoy it.
I used the pepperoncini rings.

Drizzle with the dressing 5 minutes before serving.
